Compact star
Under a compact star or compact object ( English compact star / object ) is understood in astronomy the burned-out remnant of a former star . These objects are characterized by an extremely high density and nuclear fusion no longer takes place in them. Depending on the mass of the object, it can be a white dwarf , a neutron star or a black hole . Apart from these confirmed types of compact stars, there are also other hypothetical classes which, however, have not yet been confirmed. An example of a hypothetical compact star would be the quark star .
